Spin-Manipulation geglückt

(PresseBox) (Würzburg, )
Superschnell und leistungsstark: So sollen Quantencomputer einmal sein. Doch vor der Realisierung dieses völlig neuen Computertyps stehen noch technische Hürden. Über Fortschritte auf diesem Gebiet berichten Physiker der Uni Würzburg in "Nature Photonics".

"Zum Bau von Quantencomputern sind als Informationsträger gute Quantenbits nötig", sagt der Physiker Martin Kamp. Was ein gutes Quantenbit ausmacht? Es muss verschiedene physikalische Zustände annehmen können, die beliebig manipulierbar und möglichst langlebig sind.

Um solche Bauelemente zu erhalten, beschreiten Wissenschaftler weltweit verschiedene Wege. Die Würzburger Physiker und ihre Kooperationspartner in Japan und den USA setzen auf Nanostrukturen aus Halbleitermaterialien, so genannte Quantenpunkte. Ein Vorteil dieser Festkörpersysteme zed scb Xdpxeysgdnl, iobnhok Rhtsjwwldhl bwj dauek Tmzs lc ssujznqxjyr.
